arduino optocoupler

    We can do that using relays relay is actually a switch which is electrically operated by an electromagnet. The electromagnet is activated with a low voltage, for example, 5 volts from a microcontroller, and it pulls a contact to make or break a high voltage circuit. As an example for this tutorial, I […]

arduino define

    So, by the end of this lesson, you’re going to be able to understand basically what a variable is and how to use variables and also how to spell the word variable if we’re lucky. So what is a variable and how do I make them so variables? They’Re programming tools that cut […]

arduino mega

    For that purpose, I composed the following three examples. The first example is distance measurement using ultrasonic sensor. The output of the sensor or the distance is printed on the screen and using the touchscreen we can select the units either centimeters or inches. The next example is controlling on RGB LED using […]

arduino analogread

    So what we want to know is what is the actual voltage being applied to one of the analog pins on our Arduino board now, in order to do this, we have to learn a couple things. The first thing you’re going to learn is how to use a conversion factor, it’s, actually […]

The output of the sensor or the distance is printed on the screen and using the touchscreen we can select the units either centimeters or inches. The next example is controlling on RGB LED using […]

arduino aref

    In the last video I used a trick to enhance the accuracy of the analog to digital converter in the Arduino. I thought this is worth a small video for all the guys which just want to solve this particular issue. Arduino have a built in 10, bit analog to digital converter, abbreviated […]
